IMPROVEMENT IN CARPENTEBS GAUGES.

bte Sdgrhule referrer tu in tigese tetten gnent amt mating pant nf thesante TO ALL WHOM IT MAY CONCERN:

Be it known that I, RUSSELL PHILLIPS, of Gardiner, in the county ofKennebec, and State of Maine, have invented a. newand improved DoubleRail Gra-ugo; and I hereby declare the following to be' a full, clear,und exact description thereof, which will enable others to makeend usemy invention, reference being had to the accompanying drawings, formingpart of this specification, in which- Figure l shows a side view of myimproved gauge.

Figure 2, en end view of the two slides, showing the method of theirconneetion with the stock.

Figure 3, e detached view of the end of one of the slides, showing themethod of securing,f the seme at any desired point on the stock.

Same letters indicate like parts. l y

My improvement consists of a gauge having two slides and twoknife-blade, constructed and operating as hereinafter set forth. A

a Show the two slides; A the stock; c d the two knife-brede.- Uponopposite sides of the stock, A, are mede grooves or channels, e, whichextend to the end of the stock on one end, so as to admit of the slidesbeing placed thereon. Each ofthe grooves forms two rails er tracks oneach. side of the stock. (Seefy.) Over these rails and into the groovesthe slides are itted by means of e recess in the slides and lips orshoulders near the outer edges of the recesses. hshows the recesses; thelips. Uponr the back sides of the slides ere made projections, in whichare mede the recesses, with the lips the same as on the front edge ofthe slides. These projections are seen at k. Through these projectionswork thumb-screws, m, to hold the slides at any place on the stock. Theslides are on opposite sides of the stock. The grooves, e, are wideenough to allow the parts of the slides moving therein to pass eachother without touching. By this arrangement the mechnnicis enabled tomark the Width and thickness of any piece of work with the seme gauge,one slide being set-to denote the width, the other the thickness, andthen the distances scored oli' on'the lumber with the brads. rihus theuse of more than one tool of this kind is avoided where two measurementsare to be made and lumber to be marked and Worked upon two sidesthereof. A convenientway of manufacturing is to cest the slides of metalto fit a wooden stock of a certain size.

What I oieim as my invention, and desire to secure byrLetters Patent, is

The conibinetion of the stock having the grooves and rails with the twoslides on its`opposite sides, the slides having the recesses, the lips,the projections, and thumb-screw., as and for the purposes herein setforth.l
